  • the structure can also be used as an advertising medium.
  • Patent DE 2,036,563 which describes a structure composed of several radial tubes joined at each end to a circular tube so as to form a closed tubular assembly capable of being inflated. It follows that there is no interdependence of the inflatable elements, which generates significant drawbacks, for the transport and storage of the structure. In addition, this type of structure does not allow, in a rational and safe manner, the production of large assemblies as referred to in the Request.
  • the invention as characterized in the claims solves the problem of creating a structure comprising independent and inflatable support elements, generally in the form of tubes, together forming a frame supporting a cover fabric in the form of a vault, each element having a lower end for bearing on the ground and an upper end connected to a connecting member mechanically joining the upper ends of all the supporting elements.
  • Each support element is arranged to have a curved longitudinal profile, the lower ends of which are arranged to be coupled to ground support soles capable of being weighted, while the upper ends are connected tangentially or approximately tangentially in the direction of the connecting member which is further equipped with a pneumatic supply connection to be tuned to a source of pressurized fluid and pneumatic distribution connections, in communication with the previous one, for a sealed connection with each of the upper ends of the elements support to effect a simultaneous inflation of all the support elements for automatic shaping and spatial development of the structure in combination with the soles.
  • the rigidity of the elements is given by a regulated air pressure, which facilitates the implementation of the structure, its assembly, its disassembly, its handling and its storage.
  • Figure 1 is a perspective view showing the different elements after inflation forming the basic structure of the structure, the protective fabric is not shown.
  • Figure 2 is a view similar to Figure 1 with the establishment of the protective fabric.
  • Figure 3 is a partial sectional view showing an embodiment of the coupling of the various inflatable elements to the central connecting member.
  • FIG. 4 is a variant view of FIG. 3.
  • Figure 5 is a partial sectional view showing the attachment of the elements to the ground, according to an exemplary embodiment.
  • FIG. 6 is a partial view in longitudinal section of the structure after it has been inflated.
  • Figure 7 is a cross-sectional view at schematic character of an element.
  • Figure 8 is a schematic view showing different sections of shaped elements to obtain the curved centering of an element.
  • Figure 9 is a perspective view of the main elements of the structure positioned on the ground and illustrated before inflation.
  • Figure 10 is, on a larger scale, a sectional view showing the attachment to the base of the inflatable elements, according to a preferred embodiment.
  • Figure 11 is a partial view showing the coupling of the elements to the connecting member.
  • FIG. 12 is a plan view corresponding to FIG. 11.
